The Freezer Section & Evaporator is freezing up.
The Timer, Defrost Heater & Defrost Thermostat has been replaced.
The Defrost Heater is not coming on after the Defrost Timer is in Defrost Cycle.
A 110/220/ volt test light is bright at the 2 orange & white defrost thermostat wires.
The tester is half the brightness at the 2 Defrost Heater connectors.
Please provide any suggestions on how to make the Defrost Heater come on?
